My stories ....

A dream to write a book for children has yet to happen but as the passion for my hobby took hold so did writing about slide rules - at least my often light-hearted take on various topics.

Mostly I publish my articles in the:

  • US: Journal of the Oughtred Society (JOS)
  • UK: Slide Rule Gazette and Skid Stick newsletter
  • NL: Mededeling en Informatie voor verzamelaars van historische Rekeninstrumenten (MIR) newsletter
  • DE: Rechenschieber-Brief electronic newsletter
  • xx: Proceedings of International Meetings (IMs)

All the articles, the most recent first, are listed with a short summary and a PDF download option
(n.b. some are updated/extended versions of the original article).

Use the “Browse all papers” option (most are in English but the odd one is in Dutch) or the SEARCH BY KEYWORD to find topics of interest.

Please email me if you have any comments or questions.
